John Gill Commentary Deuteronomy 10:7

"From thence they journeyed unto Gudgodah; and from Gudgodah to Jotbathah, a land of brooks of water." — Deuteronomy 10:7 (ASV)

From thence they journeyed unto Gudgodah
Which Jarchi takes to be the same with Horhagidgad, and so do most; see (Numbers 33:32Numbers 33:33) , but Aben Ezra says it is not, but is a general name, including Zalmonah, Punon, and Oboth, places the Israelites came to after they removed from Mount Hor, where Aaron died; see (Numbers 33:41–43)

and from Gudgodah to Jotbath, a land of rivers of waters ;
which the above writer takes to be the same with Beer, the well, (Numbers 21:16) and by this description of it, it was a place where there was much water.
